Patented Nov. 6; 191 *7 Application file'd September 1 11916. Serial No. 119318;

deposit from streets of municipalities; to

break hardened formation preparatory to removing the same; to provide a special mechanism for 'el'ei atuig and loading series of ii'idependent' vehicles,- andto' simplify themech'anism required for the perform} ance of'the above-stated ObJe c'ts. Y Drawmgs.

Figure 1 is a side elevation 'of'a carrier and loader constructed and arrangedin acco1da1'1ce"w1th the present inventlon;

F 1g. 2 1s a top plan view of'the same;

4 O Desomp tzon.

As seen in the drawings, a plurality of scoop-like shovels 11 are mounted on pivot shafts 12, which are supported in bearings 13 formed at the ends of cross braces 14:. The braces 14 reinforce the side disks 15 producing a drum-like construction. Each shovel has striking brackets 16 which are held against the braces 14 by springs 17.

The shovels 11 are relatively short. A series of said brackets extend across the full width of the drum formed by the disks 15. This arrangement accommodates any uneven surfaces of roads, and "avoids the total failure of all the shovels due to some irresistible obstruction in the path of one or more of said shovels. The springs 17 are F ig. 3 is an enlarged detail'view showing in vertical section a fragment of the loader ;v

provided to permitthe shovels when'strik in'g such an obstruction, to be retracted by and to' pass over the same. Inoperation and as shown in Fig; 5 of thedrawii'igs', the shovels assume a retracted or dragging angle and are thereby loaded.

When the loaded shovel is lifted by the rotation of the disks 15 out ofeng'ag'einent with the roadbed or covering thereof, the

springs '17 return the same until the brackets 16- strike the braces 1-1. This lift is sufliciently graduated as to prevent the dis-' charging of the contents of the shovel. When, however, these shovels are lifted againstthe under side of'the boot 18, they are forced backward to an excessive degree to be suddenly released to permit the'spriii'gs V 17 torotate the said shovels and to strike the brackets 16 violently upon the braces, thereby'dislodging or tossing'the load carried by the said shovels upwardly and for wardly'into the boot 18.

The drum formed by the disks l5'an d braces 1 1 is supported by a trailer frame 19,

which is carried on wheels 20; The wheels 20 operate as tractors for driving the drum, said wheels being provided with a driving pulley 21, which is connected with a driven pulley22 on the shaft 23 of the said drum" by means of a twisted belt 24s. By'the' arrangement of the belt 2% with reference to the pulleys 21 and 22, the"dr'um carrying the shovels 11, is rotated reversely to the wheels 20, or in the direction indicated by the arrow to in Fig. 5.

The boot 18 is suitably supported on the trailer frame 19 to cooperate with a belt conveyer 25 and buckets 26 with which the same is provided.

A sprocket 21 is connected with the sprocket 27 and thereby drives the conveyer 25 in the direction indicated by the arrow 6 in Fig. 5.

The buckets 26 when passing over the boot 18 are loaded with the material deposited therein by the shovels 11, and on reaching the top of the conveyer to pass over the drum 28, the said buckets deliver the load on the apron 29. The fender 30 as sists in guiding the load to the apron 29. As shown best in Fig. 1 of the drawings, the apron 29 is held in horizontal suspension by a brace arm 31 which supports a drum 32, at the outer end whereof is mounted a gear wheel 33. When the arm 31 is properly adjusted to the active service position, the gear wheel 33 is meshed with the gear wheel 34 on the cart or carrier having a body 35. The object served by the employment of the gear wheels 33 and 34-, is to drive a skeleton load-distributing belt 86. The belt 36 is driven as indicated by the arrow (Z in Fig. 1 of the drawings, and is furnished with a series of spreader bars 87, which operate to scrape the top of the load deposited in the body toward the forward end thereof whenever the top of the load extends into the path of the forwardly-moving bars 37.

The movement described which is imparted to the apron 29 results from the employment of a short belt -l9. In the modified form shown in Fig. 5 of the drawings, this belt is replaced by a longer belt 50 which is connected with the bottom drum of the conveyer rather than with the top drum.

The framework of the conveyor 25 may be of any desired pattern. That shown in the drawings is one where supporting bars 51 are employed for supporting the upper drum 28.

As shown in Fig. 1 of the drawings, the trailer is preferably self-propelled, being provided for this purpose with a motor 38, steering wheel 39, controlling levers a0, and drivers seat 41. Any suitable form of tractor mechanism may be employed. The object of the independenttractor feature to permit the independent movement of the machine to and from the field of operation.

In the modified form of the invention shown in Fig. 5 of the drawings, the machine is employed as a trailer, being operatively connected by a link a2 or other suitable means to the cart or carrier. The heater bars 43 shown in Figs. 5 and 6 of the drawings, are employed to shatter or break any lumps or masses which may have formed in the roadway or street. The bars are each rotatively mounted on a pivot bar 44, the upper ends of said bars being in juxtaposed relation to a tappet shaft 45. Rigidly mounted on the tappet shaft 45 are tappet disks &6, each of which is provided with a lug or pin 47 to strike the upper end of its companion bar 43, and to force the same forward, thereby lowering the lower end thereof as best shown in Fig. 5.

Connected with each bar 13 is a pull spring 48. The springs 48 operate to violently retract the bars 4:8 to their normal position when released by the pins a7, and thereby shatter the lumps or other massed formation of snow or other debris on the roadbed with which they come in contact.

Claim.

A machine as characterized comprising a body having carrying wheels; a rotary drum operatively connected with said wheels; a plurality of shovels mounted on said drum; a conveyor boot carried by said body in receiving relation to said shovels; and means for emptying said shovels after the same are raised above the receiving end of said boot, said means embodying a plu rality of yielding connections operable for normally maintaining the radial position of said shovels to said drum, and abutments for receiving the impact on said shovels when thrown against said boot by said yielding connections.
